    The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants. To understand how these processes work, we must first understand the energetics of water potential.

    Now complete the tasks on the list below:

    • Go to this page,,and read the following sections:
      • Movement of Water and Minerals in the Xylem
      • Control of Transpiration
      • Transportation of Photosynthates in the Phloem
      • Translocation: Transport from Source to Sink
    • Use the Glossary at the bottom of the page to help with the vocabulary for this week
    • Use the Review Questions and Free Response questions to check for understanding
